Seat-belts and child restraints in vehicles are among the "best buys" in public health. Wearing a seat-belt during a crash reduces the risk of being ejected from a vehicle and suffering serious or fatal injury by 40% to 65%. Children who are strapped in age-appropriate restraints are considerably less likely to die in the event of a road traffic crash than those who are unrestrained. Both seat-belts and child restraints are highly cost-efficient.
